Original caption: This group consists of 27 deciduous, tender, tuberous-rooted perennials, which are native to Mexico. Dahlias may be grown anywhere, but are only hardy year-round in warm climates; they can simply be grown as annuals or dug up and stored in cold-winter regions. Dahlias may also be grown in containers or tubs, depending upon the size of the variety. From these Mexican species, hybridizers have developed a multitude of forms of varying heights, as well as distinct flower shapes, sizes and colors. Dahlias range in height from about one foot to seven feet. They may produce button-sized flowers or blossoms as large as a dinner plate, in most every shade except blue. Dahlias bloom from early summer to fall and their flowers will last up to a week when cut. The flowers may be single or double, some with twisted petals. --- Image by © David Roseburg/CORBIS
